NOTE:

i To initiate the EVAP monitor, the EVAPPDC parameter must increase to at least 75% (canister

purge vent open). At this time the EVAPCV parameter displays 100% (canister vent solenoid

closed to seal the system) and the monitor begins to run. Continue driving at steady throttle

with light steering until the EVAPCV parameter displays 0% (canister vent solenoid open,

system unsealed).

z To perform the Catalyst Monitor Repair Verification Drive Cycle:

1. Complete the Vehicle Preparation listed above.

2. Drive in stop and go traffic conditions. Include five different constant cruise speeds,

ranging from 25 to 45 mph (40 to 72 kph) over a 10 minute period.

3. Stop the vehicle and access the OBD-II Readiness Monitors with the scan tool to inspect

the completion status.

4. Verify that no DTCs have been set.

MODE 1—PCM Adaptive Memory Produce Drive Mode

This mode applies to the following models:

• 2003 Mazda 6

NOTE:

i The PCM adaptive memory status can be confirmed with the RECFLAG parameter. If

RECFLAG reads “yes” the PCM Adaptive Memory Drive Mode is not necessary because the

PCM already has adaptive memory. If RECFLAG reads “no” the PCM Adaptive Memory Drive

Mode should be performed before the EGR System Repair Verification Drive Mode or HO2S

heater, HO2S, and TWC Repair Verification Drive Mode is performed.

z To perform this Mode 1 drive cycle:

1. Start the engine and allow it to warm up completely.

2. Verify the following conditions and correct as necessary:

– All electrical accessory loads (headlights, blower motor, rear window defroster, and

air conditioning (A/C) are off.

– Initial ignition timing and idle speed are within specification.

– Perform no-load racing by running the engine at 2500 to 3500 RPM for at least 15

seconds.

3. Continue no-load racing by running the engine at 4500 to 5000 RPM for at least 15

seconds.

4. Run the engine at idle for more than 60 seconds after the cooling fan stops.

5. Switch the ignition off, then back on.

6. Access the RFCFLAG parameter with the scan tool to confirm adaptive memory status:

– If RFCFLAG reads “yes”, PCM Adaptive Memory Produce Drive Mode is complete.

– If RFCFLAG reads “no”, go back to Step 1 and repeat the procedure.

7. Verify that no DTCs have been set.
